ITEM NAME:HW-516 DC 12V 24V LED Digital Time Delay Relay Trigger Cycle Timer Switch Module Product Description Description: HW-516 DC 12V 24V Dual MOS LED Digital Time Delay Relay Trigger Cycle Timer Switch Circuit Board Timing Control Module DIY Descriptions: Operating mode: P1: trigger signal, the relay is on "OP" time, and then disconnect; in the "OP" time, as follows: P1.1: signal is triggered again, invalid P1.2: signal is triggered again, the clock is reset P1.3: Signal trigger again, relay off, stop the clock; P-2: trigger signal, the relay off "CL" of time, the relay on "OP" time, and then disconnect relay; P3.1: trigger signal, the relay is turned on after the "OP" time, the relay off "CL" time, then the operation cycle, if the trigger signal period, the relay off, stop the clock; the number of cycles ( "LOP ") can be set. P3.2: without triggering signal, the relay is on "OP" time, the relay off "CL" time, and has been cycling; frequency ( "LOP") cycle can be set; P-4: signal holding function. If there is a trigger signal timing is cleared, the relay remains on; when the signal disappears, after the timing "OP" time, the relay is; if another signal during timing, timing is cleared; Pay attention: The module is an active output, the output voltage equal to the input voltage. 2.'DC + 'and' load + 'This is an internal short circuit of the poles, but' DC- 'and' load - 'poles during use can not be shorted, otherwise the load can not be controlled on and off, which is equivalent load is been carrying electricity. Timing range 0.1 seconds (min) to 999 minutes (max) continuously adjustable How to choose the time range? After setting the mode selection screen parameter value by a short press "STOP" button to select the time range; XXX. decimal point in the unit place, time range: 1 second to 999 seconds. X decimal point in decade place, Timing range: 0.1 seconds to 99.9 seconds X. X. decimal full brightness, Timing range: 1 minute to 999 minutes. For example, you wa.P-4: signal holding function. P1.3: Signal trigger again, relay off, stop the clock;. P1.2: signal is triggered again, the clock is reset. For example, you want to set "OP" is 3.2 seconds, then move the decimal point to decade place, the digital display 03.2.
